OIL-CU P.

SPECIFICATION forming part of Letters Patent No. 542,854, dated July 16,1895.

Application led May 4, 1895. Serial No. 548,122. (No model.)

Massach usetts, have invented certain new and useful Improvements inOil-Oups; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will en able others skilledin the art to which 1o it appertains to make and use the same, referencebeing had to the accompanying drawings, and to figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in l oil-cups, particularly thatclass in which the valve is controlled by a rocking lever.

My invention is embodied in the construction of the.valve-1ever, wherebythe regulating-screw designed to adjust the oil-supply zo is positivelylocked when the valve is open or in operation. By means of my inventionno check-nuts are required, and the correlation of the valve-lever andthe regulating-screw is such that no movement of the latter can take 2 5place when the valve is open 5 in other words,

when the proper flow of oil is determined upon no jar or vibrationcanpossibly change the position of said regulating-screw.

The drawings represent, in Figure 1, a ver- 3o tical sectional elevationof an oil-cup embodying my invention, showing the lever down and thevalve closed. Fig. 2 is a View in part of the oil-cup with the leverupright. Fig. 3 'is a plan with the lever down. Fig. 4 is a modi- 3 5cation. Y

In said drawings, 2 represents a sight-feed cup, so called, with theprincipal parts arranged after the most approved method. These comprisea transparent oil-reservoir 3,

4o which is mounted in a metallic base or support 4, the lower extremityof which is centrally bored for the discharge of oil and exteriorlyscrew-threaded to enable the oil-cup to be attached to the machine wherethe oil is to be supplied. A metallic disk orcap 5 surmounts theoil-reservoir. Centrally of the reservoir is a hollow tube 6, whichunites the the cup with the base, and within this tube is located fthevalve- 7 provided with a valvespindle 8, while a coiled spring. 9 servesto hold the valve closed when itis so desired. The valve spindle, in thepresent instance, is integral with the Valve, but the two may beseparate pieces, as in general. Said valvespindle projects some distanceabove and through the cap and is slotted or apertured in part at l0 toreceive a bolt or pin 12 adapted to secure the valve-lever thereto. Thelatter consists of a swinging handle portion 13 and a bifurcated endcomprising a pair of arms 14, which are preferably rounded eX- teriorlyand are attened upon their inner adjacent portions, in order to fit theupper extremity of the valve-spindle, which is likewise flattened atthis point and of a size to readily enter between the forked end or armsof the lever. This arrangement thus permits rocking of the lever, thefulcrum being the top of the cap 5; but the lever, the valve, and thevalve-spindle are all united as one piece, these elementsbeing axiallymovable, if desired.

In connection with the valve-lever and the valve-spindle is a regulatingmechanism, in the present instance in the form of a screw V15, headed at16. This screw is arranged to engage a screw-threaded hole 17, which islongitudinally bored through the end'of theY spindle. Thus, when thescrew is in position the body portion extends through more or less intothe slot 10, while the head is clasped between the arms of the lever.

From the above description it will be understood that the lift of thevalve can be regulated `by the aid of the screw 15 for the fol lowingreasons: The fulcrum ofthe lever is.

on the cap. Now, should the screw be advanced inwardly until it bearsagainst the fastening-bolt 12, the lever when moved from the horizontalatonce lifts the valve and greater movement is imparted than when thescrew is retracted. In this latter event the lever must be rocked untilthe bolt contacts against the end of the screw and a less movement ofthe valve necessarily occurs. It is to be un derstood that no rise ofthe valve can take place until the bola-which is free to reciprocate inthe slotted end of the valve-spindle, is

given a bearing or engages With the screw 15, which constitutes aportion of said spindle.

'lo avoid the use of check-nuts, which are liable to become loosenedthrough jars or vibrations of the moving machinery, is one of theobjects of my invention. It will be ob served that no check-nuts areemployed, and, furthermore, that the oil-feed is controlled entirely byaid of the screw 15. In order to positively lock this regulating device,and thus avoid any disturbance of the oil-supply when once regulated, Ihave made the dimensions ot' the head I6 such that the opposite orcorresponding sides of any pol 7gon shall just be able to enter 'thespace between the arms of the lever. Thus it will be understood that theadjustment can be regulated by varying the number of the faces onthepolygonal head of the screw 15J-that is, by increasing the number thescrew may be given a fraction of a turn and still be in position to belocked by thelever. Hence, when the valve-lever is upright the arms haveclasped the polygonal head of the regulating-screw and no vibration candisturb said screw. Moreover, the valve, valve-spindle, and valve-lever,together with the screw l5, are now interlocked and all move as a unit,and, whether these various elements are moved `axially or not, no changein the feed can take place until the lever is thrown down. Then this actoccurs the valve is closed. The screw 15 may then be adjusted to alterthe oil-supply, which can be increased or diminished as circumstancesdictate.

In order to flush the cup or to allow a full stream of liquid to flowfrom the reservoir the valve may be lifted from 'its seat by a directpull on the valve-lever when it is in the position shown in Fig. 2, orthe lever may be held temporarily at an angle of forty-five degrees orthereabout, in which position the corners of the arms rest on the capand the valve is then wide open.

What I claim isl. A valve operating device comprising a valve having avalve spindle slotted at one end, a valve lever secured to saidspindleby a bolt movable in said slot, and means to regulate the movement ofthe bolt in the slot to determine the extent of the movement of thevalve, substantially as explained.

2. In combination with a fluid reservoir, a valvehaving a valve spindleslotted at one end, a rocking valve lever secured to the spindle by abolt movable in the spindle slot, and a regulating device which ispositively clasped by the valve lever at stated times, substantially asset forth.

The combination Withan oil cup, a spring actuated valvea valve kspindlehavingy a slot therein, and a bifurcated valve lever, of a bolt securedto the lever and which engages said slot in the valve spindle, and anadjusting feed screw to serve asa bearing for kthe bolt, when the valveis to be opened, substantially as described.

lt. A valve operating device comprising a valve, a `valve spindleslotted tin `partat one end, a feed Screw adjustable longitudinally ofthe valve stem and projecting into said slot, and a forked valve `leverwhich incloses the feed screw and locks the same at stated times and`provided with aboltextending into the slotted `end of said spindle,substantially as specified.

I n testimony whereof I affix my signature in presence of two witnesses.
